LETTER AND BILL FILE.

SPECIFICATION forming part of Letters Patent No. 512,020, dated January2, 1894. Application filed April 2]., 1893. vSerial No. 471,353. (NomodeL To all whom t may concern.-

Be it known that I, VILLIAM OTTERBEIN GOTTWALS, of the city of Ottawa,in the county of Carleton and Province of Ontario, in the Dominion ofCanada, have invented certain new and useful Improvements in Letter andBill Files; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to 1o theaccompanying drawings7 forming a part hereof. v

My invention, which will be hereinafter fully set forth and claimed,relates to letter and bill tiles.

The object of my invention is a simple and inexpensive contrivanceanswering the purpose of a letter and bill file, but which is speciallyadapted for use as a file for a binding case.

Figure 1 is a perspective view of my improved ile, as forming part of abinding case and showing the arches open. Fig. 2 is a `perspective viewof a part of the file showing the arches closed. Figs. 3 and 4 aretransverse z5 and longitudinal sections through the base,

showing manner of attachment and separaration,and Fig. 5 is a detailshowing the conneations of the arch with the posts or standar s.

A strip of sheet metal, A, has its ends, a, turned up and down to formbearings for the lower cross Shanks b of the posts or standards, thelatter being either left to turn snugly 1n said bearings or secured inplace by solder or other convenient means. The standards B B are ofstout wire or tubing, bent to form two uprights or posts on a crossshank h, the rear one holding the arch and the front one being the filewire. If made of wire, the upper end of each post or upright is drilledso as to be made tubular a short distance down, adapting said ends toreceive the ends of the arch, one, b', to form a bearing and the other,b, a catch, the latter being beveled off on the inner edge to form asemi-tube or notch.

C C are the arches. They are of wire of such a thickness as to fit thetubular ends of the posts. Oneend, fitting the rear post, has

- an annular groove, c, cut in it and when inserted in the post themetal of the edge of the latter, having been previously pointed orbeveled, is pinched in so as to form a burr or collar t0 enter in saidgroove and prevent said arch from being lifted out, while being free toturn or swivel. The upper tubular end of the file wire, being beveledoff, forms an open notch convenient to receive the free end of the arch,a little sidewise pressure and guidance between the thumb and fingerbeing suffcient to lock or unlock, z'. e. engage or dis-V 6o engagethem.

D is a clasp, shown in Figs. 3 and 4 in section, which is secured to thetile board or backing E. It consists of a piece of strong tin or othersheet metal bent up on one edge at a right angle to form a rim or anged, and then about one half of the remaining part is doul bled over toform a cover d', the width of the liat base or space lbetween the frontrim d and uptnrn of the cover being just equal to 7o the width of theiile base or strip A. Two ends, d, are left on the base part forinsertion in slits in the wood or millboard forming the file back E, thelength of the cover being of course just equal to the distance betweenthe two bearings a. In this clasp the base A of the file is readilyinserted and retained after pressing down the cover d.

I -claim as my inventionl. In a letter and bill Iile, the combination 8oof a metallic base A having its ends turned up to yforth a bearing forthe posts, Athe posts B bent to form two uprigh ts on a cross shanksecured in said bearings and having its ends made tubular, the arches Ceach having one end provided with an annular groove and inserted in arear post and secured therein by having the edge of the tube upset toenter the annular groove, and the front posts having their ends beveled,a clasp D having a 9o rim d, doubled over cover d and ends d adapted forinsertion in slits, and a backing E holding said clasp, substantially asset forth.

2. In a letter and bill Iile, the combination of a metallic base havingits ends turned up to form bearings a, two pairs of posts or standardsBformed of a pair of tubes or Wires each bent to form two posts on across shank b secured in said bearings and having the tuburoo lai' endsb and band two arches C each having one end grooved annularly andinserted in a tubular end of a post and the metal of the latter closedin upon said groove, and the end b beveled on the inside to receive theother end of the arch, substantiallyas set forth.

3. In a letter and bill file, the combination, of two posts B connectedby a cross shank, a tubular end b and a tubular end b beveled off fromthe inside to form a notch, an areh C having one end grooved andinserted in the bearing Z2 and the metal of the edge thereof closed inupon said groove and the other end adapted to fit said notch,substantially as set forth.
